Only the Credeur vs. Quarry bout has been guaranteed a spot on the televised main card, which features a main event of Melvin Guillard vs. Nate Diaz.

Cantwell and Stann have fought twice before. Stann won the first meeting at WEC 26 in 2007, and Cantwell won the second meeting at WEC 35 in August 2008 to take the WEC light-heavyweight title.

The WEC ultimately ended the 205-pound class last year, and both competitors were moved to the UFC’s light-heavyweight division. Cantwell is 1-1 since the move with a first-round submission victory over Razak Al-Hassan and a unanimous-decision loss to Luis Cane. Stann, meanwhile, may be fighting for his future in the UFC. In his lone UFC appearance, the military veteran suffered a submission loss to Krzysztof Soszynski back in April.

Prior to his recent back-to-back losses, Stann had won six consecutive fights via first-round knockout.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
